CONNECTION FITTING FOR ROTARY PRESS-IN STEEL PIPE PILE

PROBLEM TO BE SOLVED: To provide a connection fitting for a rotary press-in steel pipe pile, which can connect the reusable approximately circular cross-section rotary press-in steel pipe pile and a stringer constituting a base.SOLUTION: A connection fitting 1 for a rotary press-in steel pipe pile is used to fix pieces 10A and 10B of H-shaped steel for forming upper structures of bases of upper parts of the plurality of rotary press-in steel pipe piles 20 having at least a lower end screwed into the ground and put into a penetrating state, respectively. The connection fitting 1 for the rotary press-in steel pipe pile includes a lower fitting 3 that is attached to the upper part of the rotary press-in steel pipe pile 20, and an upper-side fixing member 6 that is paired with the lower fitting 3 and that is engaged to the lower fitting 3 while pressing and holding the pieces 10A and 10B of H-shaped steel. 【課題】再使用が可能な断面略円形状の回転圧入鋼管杭と台座を構成する桁材とを連結可能な回転圧入鋼管杭の接続金具を提供する。【解決手段】少なくとも下端が地中に捩じ込み貫入された複数本の回転圧入鋼管杭２０の上部のそれぞれに台座の上部構造を形成するためのＨ形鋼１０Ａ，１０Ｂを固定すべく用いられる回転圧入鋼管杭接続具１は、回転圧入鋼管杭２０の上部に取り付けられる下部金具３と、下部金具と対を成し、Ｈ形鋼１０Ａ，１０Ｂを押圧保持しながら下部金具３に係着される上部側固定部材６とを備えて構成されている。【選択図】図１
